ALFRED DAY, OF PHILADELPHIA, PENNSYLVANIA.

EXERCISER.

To all whom it may concern:

Be it known that I, ALFRED DAY, a citizen of the United States, residingat Philadelphia, county of Philadelphia, State of Pennsylvania, haveinvented a new and useful Exerciser, of which the following is aspecification.

My invention relates to a new and useful exercising device and consistsof a frame having a plurality of rollers rotatably or stationarilymounted thereon and so supported that any one can be removed andreplaced, independently of the others.

It further consists of a new and novel roller.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

Figure 1 represents a side elevation of an exercising device embodyingmy invention. Fig. 2 represents an end view thereof. Fig. 3 represents apartial sectional view and partial elevation of a portion of the devicein detached position. Fig. 4 represents a sectional view of one of therollers.

I have found that in exercising devices it is necessary to mount therollers so that they will rotate freely but will be laterally stationaryand that the rollers are so mounted that they can be independentlyremoved and replaced.

In the drawings, I have shown a construction for carrying out. myinvention but it will be evident that changes may be made therein andother instrumentalities may be employed which will come within the scopeof my invention and I do not therefore desire to be limited in everyinstance to the exact construction as herein shown and described butdesire to make such changes as may be necessary.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings. 1 designates the frame of the exercisingdevice and consists of the front and rear uprights 2 connected by thelower side pieces 3 and the upper side pieces 4 and by cross bars 5forming a firm and substantial frame which is preferably mounted uponrollers 6, it being noted that the front cross bar 5 is connected withthe front uprights 2 at a higher point than that of the rear cross bar 5with the rear uprights 2.

7 and. 8 designate strips which are provided with recesses 9 at suitablepoints adapted to Specification of Letters Patent.

embrace or receive the cross bars 5, said recesses being situated at thefront and rear portions of said strips for this purpose.

10 designates set screws which pass through suitable openings in thestrips 7 and 8 and are adapted to be tightened against the cross bars 5for firmly locking the strips 7 and S in position.

i 11 designates a plurality of slots formed in the upper face of saidstrips 7 and 8 and which extend at an angle and are suitably situated inorder to provide journals for the rollers.

The rollers are preferably formed with the body portion 12 of wood whichis cut away a portion of its length forming a shoulder 13 and around thecut-away portion is placed the rubber 14 which abuts said shoulder 13said rubber 14 terminating a suitable distance from the end of the body12, which end is adapted to receive a sleeve ,1 5 which firmly locks therubber 14 in position, it be ing noted that the enlarged portion of thebody 12, the rubber 14 and the sleeve 15 form a roller, of equaldiameter, which prevents injury to the feet of the user.

Seated in suitable openings at opposite ends of the roller are the pins16 which pro ject a suitable distance and are adapted to be seated inthe angular slots 11 of the strips 7 and 8, whereby it will be seen thatthe roll ers are permitted to freely rotate but lateral movement thereofis prevented, it being noted that the ends of the body portion 12 aresituated preferably close to the inner wall of the strips 7 and S toprevent improper movement of the roller.

By the construction just above described it will be seen that the usersteps upon the rollers and by graspin the upper bar 4 can steady himselfand immediately start the action of running, which is permitted byrotation of the rollers while injury, as above stated, is prevented byreason of the rubber facing of the rollers. At the same time, as will beunderstood from Fig. 3, should anything occur to any one of the rollersit can be quickly removed from its slots 11 and replaced by a new onewithout disturbing any of the other rollers.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a device of the character described, a movable rigid frame, stripssituated at an in cline upon said frame, and having a plurality of slotsextending in said strips and rollers said rollers may be rotated but areprevented having ends seated in said slots, the upper from lateralmovement.
